Description

High-performance thermal insulation and colorful coatings

technical field

Background technique

Due to the country's continuous improvement and innovation and upgrading of building energy-saving technologies, the peak era of green buildings has come. The current reflective heat-insulating coatings, heat-insulating coatings, colorful coatings and other products cannot meet higher requirements at all. There are many different defects in the acceptance of national building energy-saving standards. The so-called spot checks by supervisory units, construction units, and inspection units are only walls that have been specially treated in advance, while other building exterior walls that have not been treated cannot meet the national building energy-saving requirements at all. Reflective heat insulation coatings have the best reflectivity in white, mainly by reflecting infrared rays in the sun’s heat. The darker the color, the lower the lightness value, and the lower the reflectivity. Dirt resistance and durability are its fatal flaws. Covered by dust or polluted by color, its solar heat reflectance will be greatly reduced, or even equal to zero! At the same time, it does not have the thermal insulation performance of the external wall, and the scope of application is limited. It is only used in the hot summer and warm winter areas in the south; the thermal insulation coating is in its infancy, and there is no national standard. Although it is not restricted by color, its promotion and application range is very wide.

However, the reflective heat insulation materials, thermal insulation materials, and sand-containing reflective colorful coatings currently used in the market are respectively poor in dirt resistance and durability, heat insulation materials with poor thermal insulation and heat storage performance, and sand-containing reflective colorful coatings. Coatings have poor thermal insulation performance and no metal texture and other defects, and their respective defects are difficult to meet the needs of building energy conservation durability and market changes.
